Special Issue Information

Dear Colleagues,

Providing sustainable energy to the World’s population is a major societal, technical, and scientific challenge in the 21st century as fossil fuel supplies decrease, while the World’s energy demand increases. Thermoelectric materials have potential applications in power generation devices that convert waste heat into electric current by the so-called Seebeck effect, thus providing alternative energy technology to reduce the dependence on traditional fossil fuels. Moreover, thermoelectric devices can be used as solid-state Peltier coolers, which do not use environmentally harmful fluids. Thermoelectric generators have the advantage of containing no moving parts, making them quiet, durable, and reliable. It is only recently that advances in materials development, theory, and computational tools have shown that thermoelectric devices can compete with traditional refrigeration technologies and be attractive for power generation.

This Special Issue aims to present a collection of articles describing recent advances in thermoelectric-related materials and technologies, ranging from material study to device development. Particular interest will be given to papers focused on both rapid and conventional synthesis of thermoelectric materials, the relationship of structure, microstructure, composition, processing, transport properties, and thermoelectric performance, theory and modeling, multi-scale characterization, design and applications of thermoelectric materials and devices for energy harvesting, cooling and temperature sensing, and many more.

I kindly invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are welcomed. Your participation will ensure that this Special Issue becomes an essential contribution to the thermoelectric materials and energy community. Do not hesitate to contact me if you need more information.

I look forward to receiving your contributions.

The ecofriendly tin selenide (SnSe) is expected to find multiple applications in optoelectronic, photovoltaic, and thermoelectric systems. This work is focused on the thermoelectric properties of thin films. SnSe single crystals exhibit excellent thermoelectric properties, but it is not so in the case of polycrystalline bulk materials. The investigations were motivated by the fact that nanostructuring may lead to an improvement in thermoelectric efficiency, which is evaluated through a dimensionless figure of merit, ZT = S2 σ T/λ, where S is the Seebeck coefficient (V/K), σ is the electrical conductivity (S/m), λ is the thermal conductivity (W/mK), and T is the absolute temperature (K). The main objective of this work was to obtain SnSe films via magnetron sputtering of a single target. Instead of common radiofrequency (RF) magnetron sputtering with a high voltage alternating current (AC) power source, a modified direct current (DC) power supply was employed. This technique in the classical version is not suitable for sputtering targets with relatively low thermal and electrical conductivity, such as SnSe. The proposed solution enabled stable sputtering of this target without detrimental cracking and arcing and resulted in high-quality polycrystalline SnSe films with unprecedented high values of ZT equal to 0.5 at a relatively low temperature of 530 K. All parameters included in ZT were measured in one setup, i.e., Linseis Thin Film Analyzer (TFA). The SnSe films were deposited at sputtering powers of 120, 140, and 170 W. They had the same orthorhombic structure, as determined by X-ray diffraction (XRD), but the thickness and microstructure examined by scanning electron microscopy (SEM) were dependent on the sputtering power. It was demonstrated that thermoelectric efficiency improved with increasing sputtering power and stable values were attained after two heating–cooling cycles. This research additionally provides further insights into the DC sputtering process and opens up new possibilities for magnetron sputtering technology. Full article
